A lotta great albums there, but a bit different from what i woulda' picked.
Especially Zeppelin i'm very surprised you chose the fourth album, I'd have I, II, Houses and Graffiti before IV.
Whenever I think of classic rock i think of riffs and solos. and if you'd had Led Zeppelin up there i woulda gone for that, but of the albums you have I think Are You Experienced is the most classic rock, one of the greatest albums of all time, no doubt.
